Ua tib zoo cheb los yog lub tshuab nqus tsev nrog lub txim hluav taws xob- cov cuab yeej pov thawj, zam kev tsim cov plua plav, thiab muab cov khoom khaws cia rau hauv qhov chaw kaw, sau npe corrosion- cov khoom pov tseg pov tseg rau cov khoom pov tseg kom raug raws li cov khoom siv phom sij.
3. Cov neeg ua haujlwm Sodium tert-butoxide CAS 865-48-5 yuav tsum hnav cov tshuaj lom neeg tag nrho- cov cuab yeej tiv thaiv suav nrog cov cuab yeej ua pa ntawm tus kheej (SCBA) thaum ntxuav. Tiv thaiv kom tsis txhob nkag mus rau hauv qhov dej los yog txoj kev hauv dej. Sodium tert-butoxide yog cais rau kev thauj mus los (UN3206 lossis UN2925, Hazard Class 4.2/8, Packing Group II).
Cov ntaub ntawv kev nyab xeeb
1. Sodium tert-butoxide yog cais nrog GHS teeb liab lo lus "Danger". Nws ua rau cov tawv nqaij kub hnyiab thiab qhov muag loj heev (H314/H318), yog cov khoom tawg yooj yim (H228) thiab nws tus kheej- cua sov (H251), tuaj yeem ua rau ua pa (H335), thiab xav tias yuav ua rau mob qog noj ntshav (H351).
2. Sodium tert-butoxide reacts hnyav nrog dej, tso cov pa roj carbon monoxide (hydrogen) uas tuaj yeem ua rau kub hnyiab tau. Nws lub teeb taw tes yog 12-14 degree. Thermal decomposition ua rau cov pa roj carbon monoxide, carbon dioxide, thiab sodium oxides. NFPA kev ntsuam xyuas kev noj qab haus huv yog 3 (kev phom sij hnyav), kev ntsuas hluav taws kub 3, kev ua haujlwm tsis zoo 2 .
3. Ib txwm Sodium tert-butoxide CAS 865-48-5 sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Sodium tert-butoxide kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P303+P361+P353} rau daim tawv nqaij, P{0}{9}}, P{0} rau qhov muag, P304+P340+P310 rau kev nqus pa, P301+P330+P331 rau kev noj - tsis txhob ntuav ntuav), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P235+P410 (kub, tiv thaiv tshav ntuj), P260 (tsis txhob ua pa plua plav), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
